Appenzeller cheese is a hard cow's-milkcheese produced in the Appenzell region of northeast Switzerland. An herbalbrine, sometimes incorporating wine or cider, is applied to the wheels of cheese while they cure, which flavors and preserves the cheese while promoting the formation of a rind.[2]

Appenzeller has a documented history of at least 700 years. Today, about 75 dairies produce it, each with a different recipe for their brine wash. Most of the recipes are trade secrets.[2]

The cheese is straw-colored, with tiny holes and a golden rind. It has a strong smell and a nutty or fruity flavor, which can range from mild to tangy, depending on how long it is aged. Three types are sold:

"Classic". Aged three to four months, mildly spicy. The wheels are wrapped in a silver label.[1]
